I was one of the testers during the Closed beta as well as the technical test this past week. While playing the game then I had a consistent and enjoyable 60 FPS. However, with this new build for the open beta my FPS appears to be locked at 30 FPS. I have checked both my native graphics controls using Nvidia Control panel as well as the graphical options within the game itself. Both of which indicate that my GPU is being used properly. I have also spoken with a couple other users who are experiencing this same FPS lock, all of which indicate they are using a Nvidia GTX970.
